New York City has achieved the lowest number of civilian fire deaths in its history, Mayor Michael Bloomberg and Fire Commissioner Salvatore J. Cassano announced Wednesday.

The city had 58 fire deaths in 2012. That’s four fewer than the previous record low of 62 set in 2010.

It also has recorded its fastest average ambulance response time for life-threatening medical emergencies. It’s exactly 6 1/2 minutes – a second faster than in 2011.

Emphasis mine. Like most of NBBL’s dire predictions, the concern about delayed emergency response has collapsed under the weight of time and evidence. Correlation is not causation, of course, and I’m not arguing that bike lanes have contributed to an average ambulance response time that’s faster than in previous years. But right now it does appear as if they haven’t hurt.
